No; that simple observation is compatible with other possibilities.
Are you claiming if I drop a rock and it falls to the ground this is not due to gravity?
Those were questions about this world after all. That's where New Guinea is.
May I be of assistance?
If one drops a pebble one happens to pick on a windy day at the beach it falls into the ocean 50 feet from where you dropped it. What was the cause for the pebble dropping into the ocean? Not obvious is it. It could be entirely the doing of the wind which obviously played a part since the dropped pebble wasn't thrown by you, you dropped it, remember. Certainly it is not obvious something like gravity is pulling on it. So as
bilby writes your assertion is compatible other possibilities.
OK, you reason, there should be come control over conditions which might influence the experiment?
Ao to minimize conditions like wind, you go out into the ocean, put your arm with the pebble into the ocean about a foot below the surface.. Certainly there conditions are stable. But, look, when you drop the pebble it seems to move back in tune with the waves coming and receding, and further, it takes a long tine to reach the ocean bottom only about three feed below where you dropped it.
Darn. Not obvious again. It may have been entirely due to water action associated with the waves. Again there is little to suggest something like gravity might be involved in its motion. Again
bilby is right. There are other possibilities.
Ahah, you reason. Remove all influences.
So you go out into space to the point where the there are no obvious influences on the pebble. Now you drop it and it just sits there. It doesn't rise or drop, float forward or backward, left or right. Nothing happens. Surely it there were gravity it would be optimally demonstrated under these conditions.
bilby is heard again.
So it is with the brain and the mind. It take many persons conducting experiments to come to agreement about how the brain works under all conditions. Certainly you alone are not expert enough to experience all things acting on the brain in which you've place something called mind since everybody has one and everybody seems to behave somewhat differently. Surely you understand that?
Your self evidence is actually no evidence since you are in a unique set of conditions which only you experience. We have a name for that experience. It called a phenomenon.
You problem similar to
Speakpigeon's problem with pain experience. Experimenters have shown that others sense one's pain before one senses it herself. Beyond just that experimenters agree on a particular characterization of the experience they witness and they can measure it, to the surprise of
Speakpigeon, obviously, they can characterized much more accurately than can
Speakpigeon when he gets round to 'experiencing' it.
Similarly experimenters has shown people have many awareness, some of long duration, others short, most obviously not 'aware' of the others. Similarly people have been shown to have a variety of memory types which seem in play in this and not that situation. Worse, some of those memories don't communicate with many of the awarenesses. In fact several awareness can be shown to connect with memory such that one works with speech, another with sign, but neither both or when shown to those using them, do not call up the other in memory.
You both suffer from the delusion that what you experience is true, is evidence, when it is acutually only phenomenon.
Rationalism has severe limitations. Unless everything is just so what one 'experiences' can't be replicated even in the individual so convinced one is experience true sensation or feeling.
Try this experiment some time. Get comfortable. Experience focusing on something you feel. Now concentrate and try to move it to another place. Now repeat this experiment after about four hours sleep where you are awakened by an alarm and instructed to repeat what you did earlier in the day. You probably won't even be able to find something to focus upon. Conditions. Terrible things those.
